Answer:
11. 68.6 mph
12. 5/6 page (0.83)
Step-by-step explanation:
You simply divide them (remember the word "per" means divide).


Answer:
20°
Step-by-step explanation:
One way of doing this is to find the constant of proportionality, k:
8k + 6k + 4k = 90° Then 18k = 90°, and k turns out to be 90/18, or 5.
Then the angles are 8(5), 6(5) and 4(5). The smallest of these angles is thus 20°
Answer:
Given the equation of line : 3x -2y = -18
Table values:
x y
0 9
2 12
4 15
6 18
-6 0
Now, plot these points (0,9), (2, 12), (4, 15) , (6, 18) and (-6, 0) on the co-ordinate planer, to graph the the line.
You can see the graph of the given equation as shown below.
The nearest whole number would be 18 because the 6 is greater than 5. Anything greater than five, would most likely be rounded to the nearest whole number. Hope this helped!
